Hi,
To Answer your question, we are changing from using the word sweep to ASW Search. I found out that sweep somehow infers that the search is automatic and it is not.
1) Will eligible surface units sweep automatically? Or to put this another way, is there a way to move and not sweep? For a transport to sweep seems like a pretty bad deal to me (particularly with a mandatory attack afterwards).
The Search is entirely up to the player to decide to search or not. So after movement or pressing the letter 'm' (instead of moving, attacking or repairs) the ASW search icons will appear
for you to decide which hex to start the search.

Transports may search if they want, but the probability is low that they will find a sub. The transports can not attack a sub that is revealed, but if they find one then
Air Units that are able to attack may do so up to two attacks.
2) It says you can sweep for "hidden" subs, would it be possible to sweep for (and therefore immediately attack) revealed subs as well? If not, it seems a bit paradoxical that a revealed sub is safer on the map than a hidden sub.
b) states that ASW sweeps has been reworded to say ASW search that are successful the naval unit will attack the first sub revealed. Any other subs if found will be made visible and subject to attacks by other available units that can attack. (ie adjacent naval units, Air Units)
We discussed about Air Units doing that, but it was rare that the air units would force a sub to surface when just looking like a DD would. Air units would come in and attack
once subs were discovered and could engage. Every level of ASW achieved counts not just when your unit gets upgraded for sub combat (that different) and unit also receive a bonus
for radar tech levels achieved.
So subs can be in one of 3 modes 1) Visible. This mode can happen when the sub commander attacked a naval unit, was revealed using an ASW search or because the sub ambushed a moving naval unit.
2) Ambush. This mode corresponds to the current versions where subs are invisible after moving or the next turn. If the sub ambushes a unit, in other words the enemy purposely
runs into the sub to expose the sub to Air Unit attacks.
3) Sentry. Now the player may place the sub on Sentry (Zzz) by pressing the 'z' or 's' after movement or later by using Right-click on the unit to place the sub on Sentry. Subs on Sentry will not attack. Enemy surface units can move right over the Sentry sub. So you can park subs just to be spies and attack when you want. The tactic of hunting down subs by just running into them can only happen now only if the sub player wants the subs on Ambush.
